Corrections and clarifications

• An obituary for Garret FitzGerald – Ireland's taoiseach for most of the period from 1981-87 – should have said that it was the Irish republic that US president Ronald Reagan visited in the mid-1980s, not Belfast (20 May, page 38, early editions). The piece also noted (all editions) that it was in partnership with Margaret Thatcher's government, "and notably her foreign secretary Lord Carrington", that Garret FitzGerald negotiated the Anglo-Irish agreement. Whatever Peter Carington's early contribution towards the agreement signed in 1985, the foreign secretary most intimately involved on the UK side in bringing the treaty about was Geoffrey Howe.

• Motorsport's Silverstone track was described as originally a second world war base for Flying Fortress bombers (Ecclestone absent as updated Silverstone goes on show, 18 May, page 6, Sport). "This implies it was a US Army air force base," notes a reader. "In fact Silverstone, opened in 1943, was an RAF base through its entire history ... It was home to 17 OTU (Operational Training Unit) operating Wellington bombers."
